Dataset for Siswati: Parallel textual data for English and Siswati and monolingual textual data for Siswati

Abstract

This data article presents a dataset for Siswati, a Bantu lan- guage of the Nguni group that is one of the eleven official South African languages and the official language of Eswa- tini (together with English). The dataset contains parallel tex- tual data between English and Siswati as well as monolingual data for Siswati and was developed for use as training data for machine translation systems, specifically the Autshumato machine translation project. Both corpora can also be used for development and evaluation of Natural Language Process- ing (NLP) core technologies for Siswati. In addition, the data lends itself for corpus linguistic studies. The article describes how the data was collected, what type of texts it contains and what clean-up was done. It also provides an overview of the number of words contained in the datasets.
